The Lindner Group is Europe’s leading fit-out and facade construction company, specialising in developing and manufacturing its own products to ensure superior quality and functionality. Lindner solutions for commerce, industry, transport, healthcare and entertainment can be found worldwide.
Lindner Secure is a new product range developed in response to the increasing demand for enhanced security environments. With an increasing risk of terrorist activities in today’s society, where political unrest and religious tensions are playing out on an international stage, it is unfortunately necessary to assess any public structure that sees the gathering of large numbers of people – from airports and stadia to shopping centres, hospitals and government buildings – in the context of bomb-blast security.
Lindner recognized the lack of product systems available in this field and commissioned Crossley Consult, specialist in high security and counter-terrorism material solutions, and building product
design specialist Billings Jackson Design to collaborate on the pioneering Lindner Secure range.
The intention is to provide architects and designers with the tools and systems they need to create inherently blast-enhanced environments without compromising design excellence. A comprehensive range of facades, partitions and wall claddings, suspended ceilings and raised floors, with complementary products including waste bins, which meets security best practice without detracting from aesthetic or functional performance and importantly without inspiring public fear or paranoia.
Lindner Secure products are elegant, unobtrusive and effective, integrating seamlessly into architectural schemes of all scales to ensure safety is quite literally ‘designed in’.
What happens in the case of a bomb detonation? It is not only the explosion itself but also the highly underestimated hidden danger in the surrounding environment that imperils people. Released fragments of glass, metal or even concrete surfaces act like bullets when a bomb explodes. Moreover larger parts of claddings and ceilings might collapse and their single components might come down and hit people.
The bomb blast tests performed by Lindner have revealed that the forces acting a structure depend on the environment surrounding the origin of the blast. Such forces can cause breakup and the release of fragments and particles from surrounding structures, representing a huge danger in the area surrounding an explosion.
Preventing fragmentation saves lives.

Life-savers in public buildings.
The above images show typical scenes on an airport and railway station as an exemplary environment and area of application for Lindner Secure building products. To date, unfortunately only few public buildings, which might become the target of bomb blast attacks, have blast-enhanced interior building products installed. Many might argue that there are security personnel, the police, detection systems or even body scanners eliminating the threats of such attacks. However, these measures of security can simply not cover the entire building area at all times. Many airport terminals and railway station buildings are open to the public unless you reach the security area. Especially the zones outside the security area, e.g. on an airport, could be targeted as the potential location of an attack to maximise the harming effect of a bomb blast assault.
Crowds of people standing in front of check-in, baggage drop-off desks or moving in narrow highly frequented areas with their luggage are typical target areas of terrorist attacks. In the event of a bomb detonation, the construction materials of the surrounding buildings, such as metal, glass or concrete can contribute to the debris and fragment hazard. Interior ceiling and wall cladding panels subject to blast loading can be damaged and fall down as large objects.

Do you know what is inside the waste bin on the right of the photo? – Certainly not!
Thinking of explosive devices and places to hide and detonate them, criminals might use waste bins as the perfect location in crowded places for maximising the effects of their attack and harm to people close-by. It only requires small amounts of explosive materials disguised as waste to do enormous harm when placed in an ordinary waste bin that has not been designed against such a threat.

The photos above show a typical test scenario for a suspended blast-enhanced post cap ceiling system LMD-B 100 Secure at the beginning of the explosion and after the explosion. The system successfully passed the test as the components of the ceiling system did not show any fragmentation and were securely held through connections to the ceilings substructure.
Put through the paces.
An interesting viewpoint – The camera positioned behind the Lindner Life 137 Secure glass partition with integrated glass door GTB 100 Secure records the explosion of the test bomb. Both systems performed well and passed the test against the suitcase sized IED threat.

No chance for explosive waste.
Waste bins in or in front of public buildings need to fulfi l their intended purpose and should have an adequate appearance to fi t into the overall design of the building environment. An additional requirement gaining more and more in importance due to increased terrorist activities is to prevent terrorists from maximizing the potential of harm. Waste bins can easily be used to place explosives within in the twinkling of an eye. With the detonation, fragmented bin components as well as waste items might act like bullets and even increase the deadliness of such an attack.
Lindner has addressed this potential threat and developed specially designed waste bins preventing the dangerous fragmentation. The bin has been tested with a 4 STAR security rating even in free-standing position, not additionally fi xed to the fl oor. A wide range of visual design for indoor and outdoor by using our tremendous range of surface options on metal is available to fulfi l the visual needs of the project and providing people’s confi dence in a safe environment.

Turning your visions into reality.
The facade of a building is the most important part of a building envelope when it comes to providing protection against not only climate and weather, but also from terrorist attacks such as vehicle borne explosive devices.
London Heathrow Terminal 5´s facades are made up of over 45,000 m² of glass, equating to 7,500 bespoke glass panels. These were installed in T5A and T5B, the Car Park, the Control Tower and also at the Rail Station. The high quality systems were also used for the Air Intake Towers, the Lift Towers and at the Landside Bridges. Natural light floods the buildings, bringing a tremendous feeling of space and cuts down the use of artificial lighting. Facades need to perform specific functions such as controlling the potential for overheating in summer. To help manage the temperature, the glass is coated with a film which controls the amount of sunlight entering the building. Each facade is glazed to allow greater transparency through the building and clear views of the airfield and surrounding countryside. Maximising the use of natural light also contributes to the energy efficiency of the building. Besides all these features the design also includes enhanced safety of passengers and airport staff within the terminal as parts of the facade have been designed as a bomb blast resistant construction.

Blast-enhanced wall claddings
Intelligently constructed, the Lindner Secure cladding system incorporates high-quality glazed, metal or synthetic panels that are engineered to withstand a blast impact. The panels are hooked into a gravity system. This gravity system is a combination of a robust steel basic structure, extruded aluminium L-sections responsible for the support of the panels, and minimum use of single components to ensure easy installation.
Special safety catches prevent the panels from being detached. This design feature also ensures optimum security against vandalism. Having successfully passed the blast testing procedures, Lindner Free Secure wall claddings not only stand out as a visual highlight but also provide maximum safety.

No matter what demands will be required from your ceiling we can find the perfect solution. For functionality as well as style; from concealed substructure to fully accessible. We will find the perfect solution not only for all internal and external areas but also for project-related designs in underground train stations, airports and many other specialist projects. Lindner Secure ceilings not only prevent the dangerous fragmentation when explosive is placed nearby, they also feature secured components resting connected to the building structure they are fixed to. Thus, in case of a blast, the danger of ceiling elements falling down and injuring people is eliminated.
